Wang Bin naturally didn't know what happened on Beixing. At this time, their 300-hour uninterrupted and durable test run of Tiangong Technology had already begun, and this time it was just like the previous 150 hours, using the maximum power test run.

In addition, since the 300-hour durability test run has begun, Wang Binyayao contacted the high-altitude test run and the wind tunnel verification test run. As for these, Wang Bin and Tiangong Technology have no conditions, Tiangong Technology must ask for help from the official.

So after the 300-hour verification test starts, Wang Bin immediately called General Manager Lin of 969 Group, hoping that he could think of a solution.

"Mr. Wang! I heard that your company has started a 300-hour long-lasting test run. I don't know if this is true." After Wang Bin called General Manager Lin, General Manager Lin took the lead in speaking.

"Yes, General Engineer Lin! Our Tiangong Technology's aerospace engineering has started a 300-hour durability verification test drive. If it goes well, 1,500-hour verification test drive will be carried out next. At the same time, the verification test drive of the high-altitude platform and wind tunnel verification test drive will be carried out. However, since our Tiangong Technology does not currently have this condition, I wonder if General Engineer Lin has any options in this regard?" Wang Bin said directly after listening to General Engineer Lin's words.

"Are you testing high altitude platforms and wind tunnels? Yes, we have high altitude platforms and wind tunnels, and during this period, we also have free fiefdoms and high altitude platforms. You can send the engine here in two days! I will arrange this test for you at that time, but we still have to collect it in terms of costs. After all, this is not my personal thing, but the country!" General Engineer Lin nodded and said,

"Okay, then thank General Lin!" After hearing General Lin's words, Wang Bin immediately said happily.

"By the way, Mr. Wang, there is another good news to tell you, that is, the project you applied for before has already been settled. Although you can't tell you the specific results yet, the production license of the engine you developed should be fine." Mr. Lin said.

"Really! There is no problem with the production license, it's great!" When Wang Bin heard General Manager Lin's words, he suddenly became excited, and at the same time he felt like he was putting down a burden, and he felt much more relaxed. After all, for the engine of Tiangong Technology, the most important thing is the production license.

Then Wang Bin and Chief Engineer Lin chatted for a while, and then he hung up the phone, and the excitement in his heart did not calm down for a long time.

After all, for Tiangong Technology, it doesn't matter whether they actually have a project or not. It doesn't matter whether they can get the country's scientific research funds in this regard. After all, Tiangong Technology is not short of money now. Not to mention the others, just in terms of the sale of special bearing steel, Tiangong Special Materials Company, a subsidiary of Tiangong Technology, has transferred a lot of money over the past period of time. If all this money is used to develop engines, it is definitely enough.

So a production license is what he is most worried about. Now, the engine of a manned aircraft and the engine of an unmanned aircraft are different! If the engine is finally developed successfully but does not have a production license, it would be embarrassing. After all, the engines they produce cannot be sold to the outside world without a production license.

After hanging up the phone, Wang Bin immediately walked out of his office and soon drove to the aerospace engine laboratory to tell the R&D personnel, including the wrong professor Zhang and Dai.

Professor Ka and others were also extremely excited after hearing the news from Wang Bin. After all, although this engine was not designed by them, and everything in the drawings was provided by Wang Bin, they also put a lot of effort into this engine, and they were under great pressure during the research and development and the test drive process during this period.

And now, the engine production license has finally come to an end, how could it not make them excited?

"Boss! It's really great. Our engine finally has an identity. In this way, after the 300-hour verification test drive, we can also build a production line in this area. However, there is a bit of a pity. That is, we have applied for the project, and there is no result yet. If the project can be passed, it would be perfect." Professor Kao said to Wang Bin with a smile.

"Yes, as long as the production license can be obtained, we can build a production line. As for the project approval, it doesn't matter even if it cannot be passed. After all, our Tiangong Technology is not short of this scientific research fund." Wang Bin said.

"Mr. Wang! This is not just a matter of scientific research funds. After all, once the project is successfully established, it will have huge benefits in other aspects, such as the future sales of these engines, as well as the military's recognition, etc.," said Professor Chu.

Since Professor Chu was an official scientific research unit before retirement, he was naturally very clear about these aspects. He had to pass and failed to pass the project, which would have a great impact on the future future of the engine. Not to mention anything else, just for the production license, if it could pass the project, they would not have to worry so much.

"By the way, Professor Kah, I have some good news to tell you that the tests of high altitude platforms and wind tunnels have also been settled. General Engineer Lin promised us to use their 969 Group's wind tunnel and high altitude test drive table for testing and verification." Wang Bin said to his father-in-law.

"Really? This is great. It solves the problem of wind tunnels and high-altitude test drives. As long as there is no problem with the verification data at that time, we can carry out small batch production, and at the same time, we can install our engines on the drone for testing." When Professor Kao heard the good news from Wang Bin again, Professor Kao was also very excited.

After a while, Professor Kao calmed down and looked at the engine running at the test bench full power, and he was reluctant to leave for a long time.

At the same time, not long after Wang Bin told Professor Kao and others that the news, all the R&D personnel in the entire aerospace engine laboratory learned about the good news. As participants in the R&D and test drive of this engine, they were naturally very excited, and some even jumped and shouted on the spot.

After all, they are not the professors. Many of them have just come out of school. The engine developed this time is actually the first time in their lives that they have truly participated in the development of aircraft engines.
